Refactor and optimize component logic and tests:

- Consolidate route search handling in `PosDepartmentMVP.vue` using `applyPosRouteSearch` for improved maintainability.
- Refactor tab visibility logic in `ElementTabsBox.vue` with reusable `isHidden` utility, removing redundant code.
- Enhance `SessionUser.vue` and `superUserObject.vue` modules with lazy bindings for improved initialization and performance.
- Update `NavigationMenuItemsAdmin.vue` to validate department IDs with `hasValidDepartmentId` and watchers for reactive booking count updates.
- Improve error handling logic in `HandleGlobalError.vue` and `loadOrderItems` for robustness against invalid inputs.
- Add and update regression tests for session and superuser initialization to ensure compliance with binding contracts.
- Refactor POS step components to streamline order-related logic and support immediate reactivity.
